CANDY-MANUFACTURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 386.839, dated February 23, 1886.

Application filed June 1,1885. Serial No. 167,299. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE S. COLLUM, of Hartford, Connecticut, have invented a new and useful Candy-Manufacturing Machine, of which the following description and claims constitute the Specification, and which is illustrated by the accompanying three sheets of drawings.

mentary vertical section on the line b b of Fig.

1. Fig. 5 is an enlarged sectional view of parts of Fig. 4. Fig. 6 is a siniilar view ofa modified construction of the parts shown in Fig. 5. Fig. 7 is a fragmentary plan view of the reciprocating bolt 11 shown in Fig. 5. Fig. 8 is a similar view of the tubular sliding bolt 14. with the die-bolt l4 within-it. Fig. 9 is a view of the cams 15 and 16, which may be substituted for the roller 9 or the roller 10 when the construction of Figs. 6 and Sis substituted for that shown in Figs. 5 and 7. Fig. 10 is a view looking downward of the cams of Fig. 9. Fig. 11 is an end view of a modified form of the machine minus the feedingtrough. Fig. 12 is a front view of what is shown in Fig. 11. Fig. 13 is a side view of the cam-disk 22 and the segmental groove 23. Fig. 14. is a section of that groove on the line a c of Fig. 13. Fig. 15 is a fragmentary edge view of the cam-disk 22.

The numeral 1 indicates the frame of the machine. The pulley 2 communicates motion through the shaft 3. The gear4 and the barrel 5 are keyed to that shaft. The gear 6 is worked by the gear 4, and is keyed to the shaft 7, as also is the barrel 8. The rollers 9 and 10 turn on vertical axes in proper bearings fixed to the frame 1. Two series of dies, 11, reciprocate horizontally in a series of ways, 12, in the barrel 5. These ways are bored through the barrel lengthwise at such a uniform distance from the axis thereof that they constitute a series of concave semi-cylindrical grooves in that part of their lengths which cross the deep peripheral groove in the barrel 5. Each die 11 is composed of a reciprocating bolt, 11, a hemispherical concave-faced bolt, 11", and two spiral springs, 11 and 11, the two bolts being connected by the pin 11", rigidly fixed radially within the bore of the bolt 11", and reciprocating in a short slot cut longitudinally in the periphery of the bolt 11. The entire die 11 is fixed within its way 12 by the screw 13, which screw permits the die to reciprocate under or against the action of the spring 11.

In the modified construction shown in Figs. 6 and 8 the die 14 is substituted for the die 11, the die 14. being composed of the hollow reciprocating bolt 14, the hemispherical concave-faced bolt 14.", and the spiral spring 14, all fixed in the way 12, in the manner of the die 11. The cams 15 and 16 (the latter supported by the spring 17) work one series of dies 14, while another series of dies 14 are worked by corresponding cams fixed to the other side of the machine, the two pairs of cams taking the places of the two rollers 9 and 10 when the dies 14 are used in place of the dies 11. The barrel 8 corresponds in circum-' ference and width with the deep peripheral groove in the barrel 5, and is provided with the same number of semi-cylindrical grooves as those that cross that peripheral groove. The two barrels revolve at the same speed, and with the margins of their Semi-cylindrical grooves nearly or quite in Contact, so that the pair of grooves which come into conjunction between the axes of the two barrels constitute a cylinder, as shown at 12 in Fig. 3. The feeding-trough 18 is placed adjacent to the front of the machine in such a position that a roll of candy material may conveniently be fed continuously into the deep peripheral groove in the barrel 5, and under the barrel 8.

The modified machine shown in Figs. 11 to 15, inclusive, differs from the form shown in Figs. 1 to 5, inclusive, in that the pulley 2 is keyed to the shaft 19, instead of to the shaft 3, (communicating motion to the shafts 3 and 7 through the gear 20;) and also in that the functions of the rollers 9 and 10, respectively, are performed by the cam-disks 21 and 22, re-

IOO

spectively', "in'c'onneetion with the segmental groove 28, and a corresponding segmental groove working with the disk 21 in the same way that the device 23 works with the disk 22. Both these cam-disks are keyed tothe shaft 19,].While both segmental grooves arehung loosely upon that shaft, so as not to be affected by its revolutions.

The mode of operation of this machine is as follows: The belt adjacent to the arrow in Fig. 1 communicates motion in the direct-ion indicated by that arrow. The roll of candy material in the trough 18' is continuouslyfed by the operator into the space between the bottom of the deep peripheral groove in the bar-. rel 5 and the periphery .of the barrel 8 and between the opposing concave ends of the two series of dies 11. The adjacent members of each of those series are forced inward and together by the rollers 9 and 10, operating as cams upon the inclined planes which constitute the outer ends of the dies, as illustrated in Fig. 7. The margins of the opposing die-faces meet together in this movement, and thus sever a portion of the candy material from the presented end of the roll thereof, and also press that portion into the form of a ball. Then, as the revolution of the barrels continues, the opposing dies, which have been forced together by the rollers 9 and 10, are released fromthe action of those rollers. Thereuponthe spring 11 within each die forces that die outward to its former position, that spring having been compressed by the forward movement of the die between the screw 13 and the annular shoulder on the bolt 11. The function of the spring 11 is to permit of a slight outward motion of the concave-faced bolt 11 when the bolt 11 is forced positively to its inmost limit, such slight outward motion being sometimes occasioned by the presence of a surplus of candy material between the dies. Such surplus, if sufficient, will thus prevent the absolute contact of the margins of the within them are moved together at all.

' opposing die-faces, and will make a ball of candy with one of its axes somewhat elongated. After the opposing dies have sepa-, rated the ball formed between them is discharged therefrom and drops into any proper receptacle below.

When the construction shown in Figs. 6 to 10, inclusive, is used in the machine, the cam 15 works one series of dies to the extent of operating the hollow bolts 14, while the bolts 14 are worked by the cam 16, both cams. operating against the action of the spring 14; In this case the two opposing hollow bolts 14 are forced into contact before the bolts 14 Thus a portion of candy material is severed from the-roll of candy by the cutting action of the opposing hollowbolts, and thereupon the opposing concavefaced bolts l4 are forced togetherby the cam 16 and the corresponding 5 cannon the other side of the machine. If,

new, the severed portion of candy happens to be too much'to fill the dies, the spring 17,

under each cam 16, will be compressed enough to permit a slight separation of the opposing concave-faced bolts 14" and the conse- "que'nt formation of a ball of candy with one Thus the cams on the cam-disk successively force inward the dies in the adjacent end of the barrel, and before releasing them from their action those cams transfer those dies to the segmental groove 23, the bottom of which is on the same plane as the points of the cams, that transfer being effected by means of the forward movement of the circle of dies. Thus the opposing dies are kept closed till their outer ends have passed through the segmental groove and over the cam that is passing by the end of that groove.

1 The spring 11 may be omitted from the construction of die shown in Fig. 5, and the bolts 11 and 11 may be made integral, or the bolts 14 and 14 may be made integral, and beworked by the cam 15 or its equivalent if the dies shown in Fig. 6 are used. Those two forms of die differ from each other only in the method in which they are made elastic, so as to yield to an excessive supply of candy material. When changed as suggested in this paragraph both forms of die would be identical and non-elastic. So,also, other modifications may be made in this machine without materially changing its character or its utility.

I claim as my invention- 1. The combination of the barrel 5, having a series of longitudinal ways arranged around its axis, and two series of dies reciprocating in those ways, with the barrel 8, having a series of semi-cylindrical concave grooves on its periphery, all substantially as described.

2. The combination of a series of dies arranged to revolve laterally around a common center and to reciprocate longitudinally while revolving with a cam or its equivalent arranged to make those dies to successively reciprocate, all substantially as described.

3. The combination of a hemispherical diesection, a supporting die-bolt, and a spiral spring interposed between the two, all sub-' stantially as described.

4. The combination of the hollow r'eciproeating bolt 14, the die-bolt 14", the spiral, spring 14, the cams 15 and 16, and the spring 17, all substantially as described.
